BACKGROUND

1. Field

One or more embodiments relate to a method, device, and non-transitory computer-readable recording medium for supporting relay broadcasting using a mobile device.

2. Description of the Related Art

Basically, many hardware resources (e.g., a central processing unit (CPU), a memory, etc.) are required to process video signals or audio signals. Thus, expensive high-end equipment is required to process and edit video signals and audio signals that are input through several channels in real time to produce relay broadcasting signals. Recently, as broadcasting communication technology is developed, such equipment has increased performance and has been popularized. However, resolution and quality of video signals and audio signals to be processed by the equipment also have increased. Thus, it is, in fact, difficult to process and edit a plurality of video signals and audio signals without expensive high-end equipment.

In particular, general users may generate their own videos or audios using cameras or microphones included in their mobile devices such as smartphones or tablets. However, such mobile devices may perform only simple operations (e.g., an upload or download) on video signals or audio signals generated by the users due to limitations in performance. Such mobile devices have difficulty producing relay broadcasting content obtained by combining several video signals and audio signals. Thus, there are limitations in using videos and audios that may be generated using the mobile devices in various ways.

Configuration of Repeater Device

An internal configuration and functions of main elements of the repeater device 200 will be described below.

FIG. 2 is a diagram illustrating an internal configuration of the repeater device 200 according to an embodiment of the present invention.

Referring to FIG. 2, the repeater device 200 according to an embodiment of the present invention may include a data receiver 210, a relay broadcasting content editor 220, a relay broadcasting content transmitter 230, a communication unit 240, and a controller 250. According to an embodiment of the present invention, each of the data receiver 210, the relay broadcasting content editor 220, the relay broadcasting content transmitter 230, the communication unit 240, and the controller 250 may have a program module for communicating with the repeater device 200 as at least a part thereof. The program module may be an operating system, an application program module, or another program module, which may be included in the repeater device 200 and physically stored in various well-known memory devices. Also, the program module may be stored in a remote memory device that may communicate with the repeater device 200. The program module may encompass, but is not limited to, a routine, a subroutine, a program, an object, a component, a data structure, etc. for performing a specific task or executing a specific type of abstract data which will be described according to the present invention.

First, according to an embodiment of the present invention, the data receiver 210 may receive video data and audio data from at least one photographer device 300 that may communicate with the repeater device 200. In detail, according to an embodiment of the present invention, the data receiver 210 may function to receive first sampling video data and first sampling audio data of first video data and first audio data, respectively, generated by a first photographer device 300A and receive second sampling video data and second sampling audio data of second video data and second audio data, respectively, generated by a second photographer device 300B.

In more detail, according to an embodiment of the present invention, a plurality of first audio frames divided from the first audio data are included in the first sampling audio data, and a plurality of first video frames sampled from the first video data and synchronized with the plurality of first audio frames may be included in the first sampling video data. Also, according to an embodiment of the present invention, a plurality of second audio frames divided from the second audio data are included in the second sampling audio data, and a plurality of second video frames sampled from the second video data and synchronized with the plurality of second audio frames may be included in the second sampling video data.

FIG. 3 is a diagram illustrating a configuration in which video data and audio data are sampled in a photographer device according to an embodiment of the present invention.

Referring to FIG. 3, audio data recorded by a microphone included in the photographer device 300 may be divided into a plurality of sections (hereinafter referred to as “audio frames”) 311 to 314 at a certain sampling rate to form sampling audio data. A plurality of video frames 321 to 324 captured at the same sampling rate as described above from video data taken with a camera included in the photographer device 300 may form sampling video data. The plurality of audio frames may be synchronized with, and thus correspond to, the plurality of video frames.

With continuing reference to FIG. 3, when sampling is performed on the video data and the audio data N times per second, N video frames and N audio frames may be included in the sampling video data and the sampling audio data, respectively, while the video frames and the audio frames are synchronized with, and thus correspond to, each other during one second.

As computing performance of the photographer device 300 becomes insufficient or traffic of the communication network 100 increases, it may become difficult for the photographer device 300 to perform sampling (i.e., capturing) on video data at a predetermined sampling rate in real time. In this case, the photographer device 300 according to an embodiment of the present invention may reduce computing resources required for the sampling by overlapping at least two video frames which are included in the sampling video data (e.g., using an (N-1)th video frame that was already captured as an Nth video frame, rather than separately capturing video data for the Nth video frame).

Also, according to an embodiment of the present invention, each of the plurality of video frames forming the sampling video data may be a compressed image that is generated by compressing an image captured from original video data in a predetermined compression method. According to an embodiment of the present invention, the above compression process may be performed by the photographer device 300. Accordingly, according to the present invention, it is possible to reduce a load of a communication network by decreasing a size of the sampling video data and also to concentrate computing resources of the repeater device 200 on real-time editing by passing a computing load required to compress an image to the photographer device 300.

Next, according to an embodiment of the present invention, the relay broadcasting content editor 220 may function to provide the first sampling video data, the first sampling audio data, the second sampling video data, and the second sampling audio data to a repeater through the repeater device 200. Accordingly, according to an embodiment of the present invention, a repeater that performs editing using the repeater device 200 may receive the first sampling video data, the first sampling audio data, the second sampling video data, and the second sampling audio data in the form of a preview screen, check video taken or audio recorded by each of the first photographer device 300A and the second photographer device 300B in real time, and edit the relay broadcasting content by entering a certain editing input on the basis of the previewed video or audio.

Also, according to an embodiment of the present invention, the relay broadcasting content editor 220 may function to adaptively determine quality of at least one of the first sampling video data and the first sampling audio data received from the first photographer device 300A and the second sampling video data and the second sampling audio data received from the second photographer device 300B on the basis of an editing input of a repeater (that is, an editor) that is entered through the repeater device 200. Here, according to an embodiment of the present invention, the quality of the data may include a sampling rate, a resolution, a size, etc. of the data.

For example, according to an embodiment of the present invention, a sampling rate of first sampling video data to be edited by the repeater may be determined to be higher than that of second sampling video data not to be edited. As another example, according to an embodiment of the present invention, the resolution of the first sampling video data to be edited by the repeater may be determined to be higher than that of the first sampling video data before or after it is determined that the first sampling video data is to be edited.

Accordingly, according to an embodiment of the present invention, it is possible to transmit only specific video data or specific audio data to be edited by the repeater at a higher quality than other video data or other audio data not to be edited among pieces of video data and audio data received from a plurality of photographer devices 300, and it is also possible to significantly reduce data transmission loads between the repeater device 200 and the plurality of photographer devices 300 while enabling relay broadcasting content having a sufficiently high quality to be produced.

According to an embodiment of the present invention, a control signal for adaptively determining the quality of the sampling video data or the sampling audio data may be transmitted from the repeater device 200 to the first photographer device 300A or the second photographer device 300B.

Next, according to an embodiment of the present invention, the relay broadcasting content editor 220 may function to edit relay broadcasting content including the first sampling video data, the first sampling audio data, the second sampling video data, or the second sampling audio data received from the first photographer device 300A or the second photographer device 300B, on the basis of the editing input from a repeater.

In detail, according to an embodiment of the present invention, the relay broadcasting content editor 220 may function to generate data for editing the relay broadcasting content including the first sampling video data, the first sampling audio data, the second sampling video data, or the second sampling audio data with reference to an editing input from a user (that is, a repeater). For example, the editing data may include information regarding conversion between the first sampling video data and the second sampling video data, information regarding combination between at least one of the first sampling video data and the second sampling video data and at least one of the first sampling audio data and the second sampling audio data, information regarding subtitles combined with the first sampling video data or the second sampling video data, information regarding a graphic element combined with a specific area of the first sampling video data or the second sampling video data, information regarding a sound effect or relayed voice combined with the first sampling audio data or the second sampling audio data, etc.

Also, according to an embodiment of the present invention, the data for editing the relay broadcasting content may include text-based data having a format such as XML, JSON, etc.

Next, according to an embodiment of the present invention, the relay broadcasting content transmitter 230 may function to transmit data included in the relay broadcasting content among the first sampling video data, the first sampling audio data, the second sampling video data, and the second sampling audio data received from a plurality of photographer devices 300A and 300B and data for editing the data included in the relay broadcasting content to the viewer device 400 or a storage (not shown).

According to an embodiment of the present invention, when the sampling vide data or sampling audio data included in the relay broadcasting content and the editing data are received, the viewer device 400 may play the sampling video data or the sampling audio data included in the relay broadcasting content using the aforementioned dedicated application with reference to the editing data. Thus, the relay broadcasting content intended by the repeater device 200 may be provided to a viewer.

FIG. 4 is a diagram illustrating a configuration in which relay broadcasting content is produced using sampling video data and sampling audio data received from a plurality of photographer devices according to an embodiment of the present invention.

Referring to FIG. 4, it may be assumed that data to be edited by the repeater device 200 includes first sampling video data and second sampling audio data. In this case, according to an embodiment of the present invention, when a control signal based on an editing input is received, the first photographer device 300A may increase a sampling rate for the first video data (that is, video data included in the relay broadcasting content). Thus, quality of first sampling video data 410A received from the first photographer device 300A may increase to a level (e.g., 70% to 100%) similar to that of original data. On the other hand, according to an embodiment of the present invention, second to nth photographer devices 300B to 300N, which are the other devices that have received the control signal based on the editing input, may maintain sampling rates for the second to nth photographer devices 300B (that is, video data that is not included in the relay broadcasting content) at low levels. Thus, quality of the second to Nth sampling video data 410B to 410N received from the second to Nth photographer devices 300B to 300N may be maintained at even lower levels (e.g., 5%) than the original data.

With continuing reference to FIG. 4, editing data 420 specified by the editing input may form the relay broadcasting content along with first sampling video data 410A and second sampling audio data 410B, and the relay broadcasting content produced in this way may be transmitted to the viewer device 400 or stored in a certain storage (not shown).

According to an embodiment of the present invention, the plurality of photographer devices need not necessarily be present as separate devices, and a plurality of imagers or recorders physically included in one device may also be assumed to be the photographer device of the present invention.

FIG. 5 is a diagram illustrating a configuration in which relay broadcasting content is produced using video data or audio data generated by a plurality of imagers or recorders included in one device according to an embodiment of the present invention.

Referring to FIG. 5, first video data and second video data may be generated by a front camera 510A and a rear camera 510B included in one photographer device 300 (or one repeater device 200), respectively. As described in the embodiment of FIG. 4, first sampling video data 520A to be edited may have a higher sampling rate than second sampling video data 520B not to be edited.

Also, according to an embodiment of the present invention, editing data for editing relay broadcasting content may be specified by a touch-based editing input that is entered through the repeater device 200 in real time. For example, according to a touch input that is entered in real time to a certain area of a screen on which sampling video data that is being edited is played, various graphic elements such as images, subtitles, visual effects, etc. may be added to the certain area of the sampling video data. As another example, when a horizontal or vertical sliding touch manipulation is entered while a video from a rear camera is being previewed on a screen of the repeater device 200, the display state may be switched such that a video from a front camera is previewed on the screen of the repeater device 200.

FIGS. 6A and 6B are diagrams illustrating a configuration in which editing is performed by a touch-based editing input according to an embodiment of the present invention.

Referring to FIGS. 6A and 6B, by an editor entering a touch manipulation 610 to a screen in which sampling video data is being played, various graphic elements 621, 622, and 623 may be added to a position to which the touch manipulation has been entered.

According to an embodiment of the present invention, a communication unit 240 functions to enable the repeater device 200 to communicate with an external system such as the photographer device 300 or the viewer device 400.

Last, according to an embodiment of the present invention, the controller 250 functions to control a flow of data among the data receiver 210, the relay broadcasting content editor 220, the relay broadcasting content transmitter 230, and the communication unit 240. That is, the controller 250 controls the data receiver 210, the relay broadcasting content editor 220, the relay broadcasting content transmitter 230, and the communication unit 240 to perform their unique functions by controlling a flow of data among elements of the repeater device 200 or a flow of data to/from the outside.

The embodiments according to the present invention described above may be implemented in the form of program instructions that may be executed through various computer components and recorded on a computer-readable recording medium. The computer-readable recording medium may include program instructions, data files, data structures, and the like individually or in combination. The program instructions recorded on the medium may be specifically designed for the present invention or may be well known to one of ordinary skill in the art of software. Examples of the computer-readable recording medium include a magnetic medium such as a hard disk, a floppy disk, or a magnetic tape, an optical medium such as a compact disc read-only memory (CD-ROM) or a digital versatile disc (DVD), a magneto-optical medium such as a floptical disk, and a hardware device such as a ROM, a random access memory (RAM), or a flash memory that is specially designed to store and execute program instructions. Examples of the program instructions include not only machine code generated by a compiler or the like but also high-level language codes that may be executed by a computer using an interpreter or the like. The hardware device may be configured to operate as one or more software modules in order to perform operations of the present invention, and vice versa.

According to the present invention, it is possible to produce relay broadcasting content without performing a process that requires many computing resources for video data or audio data. Accordingly, a general user who has only a mobile device that may access typical wireless communication networks (e.g., a mobile communication network such as 3G or LTE, or a short-range communication network such as Wi-Fi, Wi-Fi Direct, and LTE Direct) can easily produce relay broadcasting content.

Also, according to the present invention, a user can make various editing effects while not being significantly affected by performance of equipment.

Also, according to the present invention, video data and audio data generated by a plurality of photographer devices may be directly sampled and synchronized by a corresponding photographer device, and quality (e.g., a sampling rate, a resolution, a data size) of sampling data may be adaptively determined on the basis of whether corresponding sampling data is to be edited. Thus, it is possible to reduce a computing load of a repeater device by distributing a computing load required to produce relay broadcasting content to a plurality of photographer devices and thus widen the range of photographer devices that may participate in relay broadcasting.

Although the present invention has been described with reference to the specific embodiments and drawings together with specific details such as detailed components, the embodiments are provided only for better understanding of the present invention, and thus the present invention is not limited thereto. Also, it should be apparent to those skilled in the art that various modifications and variations may be made from the above description.
